imagen v0.1.1b released

It’s a late-coming but important release. I have made significant improvements to all areas of the library and will be stepping out of beta within the next few releases.
If you are currently using the unstable and highly-deficient v0.1b, you must get this upgrade.

Notable Improvements:

More stabilized and consistent interface

New polymorphic design for data streams

Numerous improvements to the way images are read and written

Completed read/write support for colormap Targa images with 24/32-bit palettes
